The steering post shaft 1 extends through the steering post casing 2 andthrough the lock casing 3 and through the foot board 4, and through theextension lock casing 5. The extension lock casing 5 is fitted againstthe lower front face of the foot board 4 and secured in place by bolts 6and 7. The extension lock casing 5 has a chamber 8 around the steeringpost shaft 1.

A rigid locking dog 9 has cylindrical sleeve fitting closely upon thesteering post shaft 1 and secured in place by cap screws 10 and has alongitudinally extending slot 11 to receive a movable locking dog 12, sothat when the movable locking dog 12 is in the slot 11 the steering postshaft 1 cannot be rotated. V

The movable locking dog comprises a solid rectangular block 13 and astein 14 extending upwardly from the block 13 in line with the outeredge of the block.

The extension casing has a cylindrical 5 portion 15 in which the rigidlocking dog 9 operates and a neck 16 in which the movable locking dog 12operates, said neck 16 being shaped to allow the locking dog 12 to moveinaplane parallel with vthe steering -post shaft 1 and to hold the dogfrom rotating or moving laterally as required to hold the steering postshaft 1 locked.

'Thelock casing 3 has a semicircular portion 17 forming an extension ofthe steering post casing 2 and a rectangular portion 18 extendinglaterally from the portion 17 and forming a housing for the lockmechanism 19. The portion 18 of the lockcasing 3 is in line with theportion 16 of the extension casing 5. y we 'A flange 20 extendsoutwardly all the way around the lock casing 5 and a mating flange 21extends outwardly all the way around the lower end of the casing 3 andthe bolts 6 and 7 extend through the flange 20, through the matingflange 21 and nuts 22 are applied and the bolts riveted to form heads 23to hold the nuts from being removed. Of course, the lockmeclianism 19 ismade up and placed in the casing before the nuts 22 are applied. 1 v wThe lock casing 3 has a neck portion 2 1 matchingwith the nut portion 16of the extension casing, so that the movable locking dog 12 will moveupwardly to a point above the upper end of the rigid locking I dogreotangularportiorr1:3 of the lock""casin'g"3 is larger than the neck;pore:

The combination operating member 39 extends freely through thecombination plates 29 and through the bearing plate 31 and through thespring seat support 36 and has a tapered end 40 and a supportingshoulder el. The tapered upper end 40 is flat one way and fits in theopening in the spring seat 37 with the spring seat 37 resting upon theshouldertl.

The'opening through the spring seat support 36 is flat to fit the flatmember 39, so that the member 39 will not rotate in the spring seatsupport 36, and so that the member 39 may go up and down through thespring seat support 36 and not through the spring seat 37.

The expansive coil spring 12 is mounted in the chamber 38 against thespring seat 37. A head 13 is fixed in the upper end of the spring casing35 against the spring 42 and a bearing plate 44 fits in the container 26and has a central opening in which the spring casing 35 rotates.

A shaft 45 has a rectangularlower end fitting in a socket 46 at thecenter of the head 43 and the shaft extends upwardly and is journaled inthe head 28. A bevel pinion 17 is fixed upon the upper end of the shaft45 below the head 28.

,The details of the,combinationoperating. member 39; Lare shown in ings,I I9 and The body'55 is straight from the'shoulder 11 downwardly andrectangular in;cros s sectia; A re e sffi. s named, "in t o he narrowsides near the lowerfend and a bore 57 extends from the upperpart' ofthe recess straight through the body, v V I A pin hole 53 is formedthrough the body crosswise of the recess 56 near its lower end. A, lug59vextends downwardly from the end of the body and has a transversepinhole 60. Referring to the Figs, 2 and 5, a bell crank lever 61 ismounted inthe recess 56 eabedrin e r e P at y a ri kinserted through thepin hole 58 and through the angle of the lever. A short arm 63 of thebell crank lever is substantially horizontal and a long arm 6% issubstantially vertical, there being a vertical slot 65 through the upperend of the long arm 64.

A combination selecting finger 66 is slidingly mounted through the bore57 and slidingly connected to the arm 6% by a pin 67 inserted throughthe end of the finger and through the slot A. swivel head 68 isconnected to the stem lei by a screw 69 inserted downwardly looselythrough the head 68 and tapped into the stem 14 so that the head willrotate freely.

The lug 59 extends into the upper end of the head 68 and is connected tothe head by a pin 70 inserted through the head 68 and through the pinhole 60, so that when the hand wheel 53 is operated in either directionthe combination operating member 39 carrying the combination selectingfinger 66 will be rotated.

The combination plates 29 have central openings 71 large enough to allowthe arm 66 to pass freely up and down and to allow the finger 66 to passfreely up and down when the finger is moved inwardly to tilt the bellcrank lever 61 to swing the long arm to the left, as in Fig. 5, and thefinger 66 is longenough so that when the bell crank lever 61 vertical,as in Fig. 5 the outer end of the finger 66 will not pass up and downthrough the openings 71.

A spacing band 72 is placed below the combination plates 29 and a stopplate 73 is placed below the spacing band 72, the openin T1- in the stopplate being small enough to prevent the long arm 63 of the bell leverfrom passing downwardly below the stop plate, so that when the parts arein position as shown in Fig. 5 with the outer end of the finger 66resting on the combination plates 29 and something happens, as themisworking of the combinations, to push the finger 66 to the left until.the finger will pass through the opening 71, then the tension of tlspring will push the movable locking dog 13 downwardly until the shortarm 63 of the bell crank lever 61 strikes the stop plate 73, and themovable locking dog 13 will engage the rigid locking dog 9 and thesteering post shaft 1 is locked and cannot be unlocked without workingthe combinations to cause the finger 66 to find its way back to the topof combination plates 29.

The details the COKE-.QlflittiOll plates 29 are as follows:

When the combination finger 66 is moved inwardly and the member. 39drops to lock the dogs 13 and 9 together the arm 68 strikes the stopplate'73 and the. finger 66 is extended over the combination plate 75and under the combination plate 76. The com- 1 tin) emu bination plate75 is a smooth rectangular plate having a central opening 71.

The combination plate 7 6 is shown in detail in Figs. 16 and 17 andcomprises a rectangular plate having a central opening 71, a recess '77formed from its lower face, a rib T6 zpon its upper face, a slot 79extending from the recess 77 to the upper face, and an inclined shiftingtongue at the lower side of the slot 79. The combination plate 76 fitsfiat upon the combination plate 75 and the finger 66 operates in therecess 77 and if the hand wheel 53 is operated in the right directionthe finger 66 will pass up the tongue 80 through the slot 79 to the topof the combination.

A groove 81 in the lower face of the outer end of the finger 66 fits thehead 78. Proper manipulation will cause the finger 66 to pass to the topof the combination plate 76 and then further manipulation will cause thefinger 66 to pass to the top of the combination 82.

The combination plate 82 is shown in detail in Figs. and 2% and consistsof a flat plate fitting upon the combination plate 76 and having acentral opening 71 and a recess 88 in its lower face and a slot 84:extending from its lower face to its upper face, there being a lefthanded pivoted tongue 85 bearing upon the combination plate 7 6 to guidethe finger 66 upwardly through the slot i. The combination plate 7 6 isprovided with a throw off lug 86. The throw o'lf lug 86 extends upwardlyand inwardly from the upper face to the edge of the opening '71 so thatif the combination operated to bring the finger 66 against the throw offlug 86, the finger will be pressed inwardly and will fall to the starplace. The throw off lug 86 has an inclined or curved inner face toserve as a cam to press the finger 81 inwardly. if the combination isproperly worked the finger 66 will pass up the pivoted transfer tongue85 to the top of the combination plate 82.

Further proper manipulation of the combination operating hand wheel 53will cause the finger 66 to pass to the top of the combination plate 87.The combination plate 87 is shown in detail in Figs. 21 and 22 and isthe same as the combination plate 76 except that it has a left handedtransfer tongue 88 and the throw off lug 86 is omitted. Propermanipulation will cause the finger 66 to pass to the top of thecombination plate 89.

The combination plate 89 is shown in detail in Figs. 23 and 2e and isthe same as the combination plate 82. Proper manipulation will cause thefinger 66 to pass to the top of the combination plate 91.

The combination plate 91 is the same as the combination late 87 with thethrow ofi' lug 86 added. roper manipulation will cause the finger 66 topass to the top of the combination plate 92. The combination plate 92 isthe same as the combination plate 89 except that the transfer tongue isturned to a difl'erent quarter. Proper manipulation will cause thefinger 66 to pass to the top of the combination 93 which is the same asthe combination plate 76. Then the finger will pass to the combinationplate 94 which is the same as the combination plate 82 with the transferslot in a different quarter and the throw oil lug'86 added. Thecombination plate 9 1 is shown in detail in Figs. :25 and 26.

Continued manipulation of the handwheel 53 will cause the finger to passto the top of the combination plate 95, then to the top of thecombination plate 96, then to the top of the combination plate 97, thento the top of. the combination plate 98, then to the top of thecombination plate 99, then to the top ot' the combination plate 100, andthen to the top of the combination plate 101 and the steering shaft 1 isunlocked and free to operate the automobile.

A spring catch 102 is provided upon. the combination plate 101 to holdthe finger 66 steady during the operation of the vehicle. In assemblingthe combinations a record is kept of the mix up of the combinations andthis record is read upon the dial 51 asthe hand wheel 53 is manipulated.to Workout the combination.

Any misworkin g of the combination from start to finish will cause thecombination to drop and the work must start from the beginning again.

The combination plates 95, 97 and 99 are the same asplate 92, thecombination plates 96 and 98 are the same as plate 92, and'thooinbination plat 100 squareand of courseh .ve four quartersand eachcombination may be changedi to ,four

It is obvious that the lock thus constructed and applied cannot beeasily picked or unlocked by unauthorized persons.

It is thought that the operation is obvious from the foregoingdescription and drawings.

Various changes maybe made Without departing from the spirit of myinvention as claimed.
